PATENT EDUARDO RABONI, OF MONTEVIDEO, URUGUAY.

SHOE.

Application filed July 13, 1922. Serial No. 574,659.

T 0 all whom it may concern:

Be it known that I, EDUARDO RABONI, a citizen of the Republic ofUruguay, and a resident of Montevideo, Uruguay, have invented certainnew and useful Improvementsin Shoes, of which the following is aspecification.

This invention relates to a novel shoe construction and aims to producean article which will be light, cheap to manufacture, of few parts,which will accomodate itself to the feet of the wearer, and which may beput on and taken off without undoing the fastening means.

Another object of my invention is the provision of a material from whichthe shoe is made, which is elastic in its nature, but having the maximumamount of wearing quality.

Still another object of my invention is the utilization of this materialof which the body of this shoe is composed for a closure means.

I have illustrated in the drawings one em- 26 bodiment of my inventionwhich has been found to be satisfactory, but I do not wish to be limitedto the structural details as obviously these may be carried out in amanner other than that shown.

In these drawings:

Fig. 1 is a perspective of a finished shoe according to my invention.

Fig. 2 is a plan view of the insole and supplemental strip with threespring elements.

Fig. 3 is a transverse section on the line 3-3 of Fig. 2.

Fig. a is a detail of a spring element showing a covering.

My invention consists primarily in the provision of a tightly woundspiral spring which may be of any desired size or material having thesequalities. This spring member I utilize to form the shoe upper by ar- 45ranging a plurality of these members side by side, extending from oneside of the shoe to the other, the loops thus formed increasing inextent from the ends towards the center, as may be found desirable toaccommodate the foot of the wearer.

Certain other instrumentalities are provided whereby the spring membersare attached to the shoe sole which will be more fully hereinafterdescribed.

Referring now more particularly to these drawings, I have illustrated ashoe lnsole at l which is preferably of metal. A spring member 2composed of tightly wound concase of the insole, except that it entersthe convolutions from the opposite side with the result that the springmember is prevented from having outward or upward movement. The strip 3may then be socured to the ordinary outsole in any de sired manner.

If found desirable a thin, flexible, metallic sole might be substitutedfor the ordinary sole, thus forming the entire shoe of metal.

Such a shoe is of extreme simple construction and where the springmember of line gauge is used, will be of a lightness, less than that ofthe leather shoe, and favorably comparable to one of cloth or satin.

It will be obvious that such a shoe requires no fastener inasmuch as theinherent spring quality of the member 2 tends to keep the shoe on thefoot. This spring quality above referred to will also allow the shoe tostretch to accommodate itself to the various movements of the wearersfoot in walking, thus insuring great comfort and ease in walking.

It may be found desirable to cover the spring elements forming the shoeupper with cloth, or individually with a woven tubular member. Thisobviously will protect the stocking of the wearer from undue wear, whileat the same time affording a variety of colors, designs, and materialswith which the exterior of the shoe may be ornamented.

I claim:

1. A shoe including a sole and an upper secured thereto said uppercomp-rising a series of individual disconnected strands of sprinmaterial.

2. n combination, a shoe having an insole, a shoe upper composed ofspring material secured to the insole and a supplemental strip adjacentthe insole, said spring member being held between said supple mentalstrip and said. insole.

3. The device of claim 2 said strip being secured to the outsole. l

t. In combination, a shoe having a sole and a. plurality of loops ofspring material extending from side toside or' said sole.

5. The device of claim l, said spring material including a tightly Woundspiral spring.

6. In combination. a shoe including an insole, a supplemental strip inproximity to the insole, secured to an outsole, a length of springmaterial including a tightly WOllIld ture.

EDUARDO RABONI.
